摘要
利用300MHz单向数字传输系统可以把相距30 m左右的移动物体上的待传数据传送到固定的接收地点。在一款廉价的300MHz单向数字传输系统的研制过程中,本文对开关调制方案的采用、系统的工作原理、电路的设计、元器件的选择等方面进行了阐述,对该系统主要组成部分———发射电路与接收电路进行了分析、计算、论证与实践。
Using a system of 300 MHz data unilateral transmission can transfer data to data sink from moving target 30m away. In course of a development of low-cost system of 300 MHz data unilateral transmission. This paper expounds about selection of keyswitch control, working principle, design of circuit diagram, component select etc. It emphasized on two major parts of this system-the circuit diagram of transmit and receive, and carry out the analysis, calculation, argument and fulfillment.
